Associated RC18T 55T Titanium Main Gear by GPM TAR055TA  [TAR055TA]

Associated RC18T Main Gear (55T)

This is an RC-scale 55T main gear produced for the Associated RC18T platform, finished in titanium and supplied with an alloy adaptor. The component serves as a direct replacement spur gear for the 18T chassis where the 55T tooth count is required for gearing choices and drivetrain setup.

Installation notes: the part is supplied as a 1 set unit intended to replace the stock spur gear and use the included alloy adaptor to fit the gearbox interface. Check gear mesh and clearance with your motor pinion and wave washer stack when fitting, and verify center mesh under normal suspension droop to avoid binding.

Tuning role: swapping to this titanium main gear is primarily for durability and consistent tooth profile under load, while the alloy adaptor ensures correct seating in aftermarket gearbox housings. Use it when testing gear ratios, improving wear resistance, or when a precise 55T count is required for lap-time or driveability changes.
